ZnS:Ag PHOSPHOR POWDER
EJ-600
Silver activated zinc-sulfide, ZnS:Ag, is a free-flowing white fluorescent powder having exceedingly high scintillation efficiency. It is primarily used for alpha particle detection. The most common detector format is a thin flat plate of inert glass or plastic to which the ZnS:Ag is affixed in a thin uniform layer on one side. Such scintillating screens provide very high intrinsic detection efficiency for alpha particles while having very low sensitivity for beta particles and gamma rays.
